### 4.1 Introduction

Section 4.2 describes a simple mechanism to reject old duplicate segments that might corrupt an open TCP connection; we call this mechanism PAWS (Protect Against Wrapped Sequence numbers). PAWS operates within a single TCP connection, using state that is saved in the connection control block. Section 4.3 and Appendix C discuss the implications of the PAWS mechanism for avoiding old duplicates from previous incarnations of the same connection.
